- •
During the breeding season, the abundances of Skylarks are dynamic.
- •
Dynamic abundance is computed by the Moving Window Abundance methods.
- •
Functions over a specific period of time characterise the dynamic abundance values.
- •
Agricultural landscapes and crops differ significantly in the abundance course.
- •
Birds as bioindicators should be standardised by parameters of dynamic abundance.
